off grid solar, house batteries for rv, camper, boat. If you've got 12 V devices you can run that directly from the battery without any inverter which is nice.
I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.

Lol. These were NEVER $1,055. These "sale" prices are ridiculous. Like it's still a good deal. I bought two of these at ~$300 each last year and love them, but please they need to stop saying they're marking it down 75%!

No. These are NOT starter batteries. That isn't how it works.

Community Reviews

This 12V 280Ah LiFePO4 battery is being used as affordable house, RV, boat, camper, and off-grid storage, with Bluetooth monitoring and enough capacity for serious loads. It is praised for running 12V devices directly, pairing well with solar, and scaling into 24V or 48V banks for larger systems. Real-world reports include trolling motors, backup power, and even air conditioning, though runtime drops fast on heavy AC loads. It is not a starter battery, and charging or wiring often needs the right lithium charger, fuses, and connectors.

  • The battery can be a strong value for energy storage, with multiple reports describing unusually low pricing compared with typical LiFePO4 battery pricing.

    LeakyAneurismantsam9alphawave

  • The battery can integrate into solar and EcoFlow systems, including setups that charge from solar and feed EcoFlow Delta units via XT60i inputs.

    DealMongrDealMongr

  • The battery can run 12V devices directly without an inverter, which can improve efficiency versus stepping down from a higher-voltage power station.

    LeakyAneurism

  • The battery supports real off-grid and RV use cases, including running an air conditioner for about eight hours in a trailer setup.

    proudfoot

  • The battery can work well for backup power with an inverter, including a reported longest outage of about fourteen hours while still leaving remaining battery juice.

    JuddJ

  • Coupon and checkout reliability can be inconsistent, including reports that promo codes fail to apply or stop working during checkout.

    wildbird12paul2112cx1pootie22paul2112cx1

  • The battery is not intended for vehicle cranking, and it lacks the CCA needed to start a car.

    mblitchCoreyM1264Someguy15

  • The battery can drain quickly with high-power AC loads, and a 13500 BTU unit running constantly was estimated to last under three hours.

    TheNetGuytaz112576

  • The battery may require careful charging compatibility, since some setups report Bluetooth not working and the battery not registering full state of charge with an AC-to-DC controller.

No. This is way bigger than a car battery. It's for power storage. I got two of them in my trailer. Works well - you can run the air conditioner for 8 hours off them.
Interesting, you talking travel trailer? Do you replace the battery that is on the trailer?

No, these are not starting batteries, which require several hundred amps.

I used the code AEUS56 for $56 off from $287, then add $21 for tax. I see that code is expired now and it's $305 now.

It's about the same size as a car battery, but it definitely can't be used as such.
It doesn't say where to use. Seems dangerous people use this on car

Slick deals need to stop doing this, it's misleading.

I never got it to work but I was able to use USCD35 for $35 off. Had to pay $26.52 in tax (not sure if this is tariff or other type of tax, delivering to California).Total was $287.37+$26.52-$35=$278.89 still a great deal.I also bought a pair of 2/0 AWG 30cm cables for only $1.69 after tax which is kind of insane. I won't get my hopes up, but for less than $2 I'll take the risk lol I already have another one of these batteries so I'm hooking them up in parallel. So a whopping total of $280.58 for the battery and a pair of 2/0 AWG cables. Not bad. Below is a listing of the cables.https://www.aliexpress.us/item/32...pt=glo2usa
While still an excellent price for those cables, those are 2 AWG, not 2/0. 2/0 is thicker and can handle more amps with less resistance. I couldn't find a listing for 2/0 on Ali Express. I got 4 batteries from the eBay deal that need to be be hooked up together as well.

Yes, definitely. I now have 4 of these in a 25.6V series parallel bank configuration providing power to an Eco-Flow Delta 3 Plus via the XT60i inputs.I charge the battery bank from solar through a Redodo charge controller.
Can you/do you charge the eco-worthy battery array while at the same time discharging to the Eco Flow Delta 3 Plus? Meaning no disconnects are needed between charge and discharge?

Great point. 2/0 has twice the area as 2 AWG. Always good to check copper clad aluminum vs pure copper as well to make sure the cables can handle the current. The consequences of miscalculating these things can be dire.

No, it will destroy your alternator
How so? I've been using one in my motorcycle for almost 2 years with no issues at all. They are compatible with AGM battery charging. Only issue is if your system does a float charge which is bad for LiFePO4, but the BMS will cut off charging once it reaches the maximum voltage.

Yes. In my case I have the solar charge controller charging the batteries and I use the charge controller load out to feed the Eco-Flow Delta 3 Plus XT60i input(s). No disconnects/reconnects are required.

can i use this to charge my ecoflow power station?

Im thinking of connecting it using alligator clips from 12v batt to xt60 to the back of the power station. not sure if this will work and advisable.
yeah, i use the ecoflow alternator charger paired with one of these eco-worthy batteries and i'm able to charge the ecoflow delta pro or the 12v eco-worthy with it with just a click of the app.

Once bms stops accepting charge amps from alternator, alternator overheats and gets fried because it cant discharge....

Great deal except you have to deal with Aliexpress that wont refund your money when the items dont show up. If you buy anything from this scammy company make sure you have some sort of buyer protection.
